Looking beyond biodiversity to explain community invasibility
Most studies suggest that diversity is an effective barrier to plant invasion. However, these may be limited in their generality, because they involve relatively small numbers of species or examine only short time periods. Ecology Letters, February introduces a study by Meiners et al who analysed data from 42 continuous years of sampling old field succession. They found that when richness was related to invasion dynamics, it enhanced rather than impeded invasion. (2004-02-05)

Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, including productiveness or ability to resist invasion by exotic species. Many grass species host fungi in their leaves rendering them more resistant to herbivory, drought, and competition. In Ecology Letters, January, Rudgers et al. investigate whether these endophytic fungi can modify how diverse communities resist invasion. (2003-12-10)

Study reveals new data on how lyme disease is spread
The results of a five-year study, published this week in the Annals of Internal Medicine by researchers at New York Medical College, reveal intriguing new data on the spread of the Lyme disease bacteria through the blood stream. Researchers concluded that the high rate, early onset, and prolonged duration of risk for blood stream invasion probably explain why untreated patients with erythema migrans, the tell-tale bulls's-eye rash, often develop complications distant from the tick bite location. (2005-05-02)

Invasions by alien plants have been mapped in European Union
Biological invasions are one of the major threats to biodiversity and in many cases they have considerable impact on economy and human health. For their effective management it is important to understand which areas and ecosystems are at the highest risk of being invaded. (2009-01-22)

(2014-10-24)

Freshwater snails are surprisingly fast-moving invaders
A new study sheds light on some very fast snails and their success at long-distance colonization. Introduced into the rivers of the Martinique islands less than twelve years ago, the freshwater snails have already colonized the watersheds, an astounding feat considering that the snails need to rely on passive dispersal by birds, cars and cattle to jump over the dry land that separates the riverways. (2006-12-04)

Biophysics: The art of worming through tight spaces
How active matter, such as assemblages of bacterial or epithelial cells, manages to expand into narrow spaces largely depends on their growth dynamics, as Ludwig-Maximilians-Universitaet (LMU) in Munich physicists demonstrate in a newly published study. (2019-08-29)

New chemo cocktail blocks breast cancer like a strong fence
A Northwestern University Feinberg School of Medicine researcher has developed a new chemotherapy cocktail that cuts the spread of breast cancer by half and is the first drug to attack metastasizing breast cancer. The disease becomes fatal when it travels outside the mammary ducts, enters the bloodstream and spreads to the bones, liver or brain. Currently, there are only drugs that try to stem the uncontrolled division of cancer cells within the ducts. (2009-10-06)

Striking back at biological invaders
A special news section in the 17 September issue of Science highlights how scientists are fighting back against invasive species--exotic plants and animals that colonize and often wreak havoc on native ecosystems.

New study finds multiple invasions increase green crab's Canadian range
The recent rapid expansion of the European green crab's range in the Canadian Maritimes had biologists wondering if global warming or an adaptation to cold was responsible. Using molecular tools, biologist Joe Roman, conducting research at Harvard University's Department of Organismic and Evolutionary Biology, found that it was the injection of new lineages in northern Nova Scotia that was responsible for the crab's success in the north. (2006-06-20)

U-Michigan scientists observe deadly dance between nerves and cancer cells
In certain types of cancer, nerves and cancer cells enter an often lethal and intricate waltz where cancer cells and nerves move toward one another and eventually engage in such a way that the cancer cells enter the nerves. (2015-04-28)

Biosecurity strategy needed for China's Belt and Road Initiative, researchers say
China's Belt and Road Initiative (BRI), launched five years ago, includes more than 120 countries, linked by six proposed land-based Economic Corridors between core cities and key ports along traditional international transport routes. But, as new evidence reported in the journal Current Biology on Jan. 24 shows, the risk of introducing invasive species into new areas is substantial as it would threaten native species and biodiversity. (2019-01-24)

Mountain plants unable to withstand invasion
An international research team has studied the distribution of plant species in mountainous environments. The study shows that mountain plant communities are not particularly resistant to invasion by exotic species.
